Thanks for the advice. I did switch to f/t ASF, and I'm getting a consistent and almost immediate strike/constrict response with just minimal "zombie dancing" required. I initially tried soaking his first ASF in chicken broth like I did with the mice, but for the rest I haven't done that, and he doesn't seem to care either way. I'm guessing he really likes his new dinner, and he was telling me that if I wasn't going to give him real food, he wasn't going to do the whole song and dance. :-)
